PSA:
When starting a new save time is precious. Having a brand new Sim straight from CAS already aging can be frustrating.
There was a bug that caused existing Sims to age when being restyled in CAS. That was Fixed in Patch 1.47.51 but then a new one appeared. Brand new Sims are coming out already aged at least two Sim days. That means less time to perfect all those skills and complete aspirations.
This is a friendly notice to check the age of newly created Sims or ones that are restyled in CAS.
There is a room I uploaded for something else that is simple 5 youth potions.
Use them as you see fit.
Happy Simming to all! 5 Youth Potions[FIXED] Sim ages while in CAS[OPEN] Age groups start with random days added
